Hellfire Within

My entire family is trapped inside a burning mansion, and the flames will engulf the whole place in 3 minutes. I must rescue them all, but something strange happens in the lobby—when I save one of my family members, they transform into a demon that ignites unquenchable fire around them. Amidst the chaos, I find a mysterious round object, and the moment I touch it, the fire created by the demon vanishes.
